google/ExoPlayer

This system is a comprehensive media playback and processing library for Android, designed to handle a wide variety of audio, video, and container formats. It provides core playback capabilities including streaming, offline downloads, and ad insertion, while also supporting advanced features like video post-processing, 360-degree video stabilization, and hardware-accelerated decoding for codecs such as AV1, VP9, and Opus. The codebase has been significantly refactored to migrate from the legacy ExoPlayer API to the modern AndroidX Media3 namespace, emphasizing modularity, testability, and robust session management.

This period focused on stripping out legacy ExoPlayer V2 components, including the old chunk-based architecture, deprecated utilities, and Eclipse build files, while simultaneously introducing native C++ extensions for VP9, Opus, and FLAC. The work also involved migrating the codebase to the AndroidX Media3 namespace and updating the Gradle build system, signaling a transition toward a more modular and modern API structure.
